Logistics of have an outdoor/ hiking wedding?

It's not unheard of to have a different day reception, maybe a little unusual but definitely not heard of.
In terms of the ceremony you'd have to be aware of abilities and how long ect, as an avid hiker I am sure you're aware you are only as fast as your slowest hiker.
You could do a morning hike/ceremony and evening reception.
Private ceremonies and large receptions do happen. Just make it clear on the invite that you're inviting people to the reception of (name) so they don't go in expecting a ceremony.

Definitely not UNheard of. Ugh spell check!

There are some questions to ask. Is the ceremony spot an hour's hike from the reception or is there some driving then a shorter hike? What are the ages of your guests? For the older and younger guests even a shorter hike may be too much. Also, I'm not sure what state you are in, but do you have any guests coming from significantly different altitudes? I ask because my uncle got married at the peak of the ski resort Snowbird and then most of the guests hiked down. Well I'm a Jersey girl coming from an altitude of about 1100'. The peak at Snowbird is about 11300'. I ended up with altitude sickness and was absolutely miserable.

I think your idea is great. It sounds very special, but depending on your guests, it may be better for you to do a ceremony with just you two (or possibly include immediate family if they are up for the excursion) and then do the reception after. It doesn't necessarily need to be the next day though. It could be that evening.

You could also leave it up to your guests if they want to make the hike, but you run the risk of someone thinking that they can do it physically and have it be too much.

I think you can make it work, just keep the abilities and stamina of your guests in mind when deciding about who attends the ceremony. I wouldn't worry too much about stepping on toes. If your family and friends know you, they know that this is something that you enjoy and should understand if the reason you aren't having them at the ceremony is their comfort and safety (but we're only having parents and siblings at our ceremony and partying the following month, so maybe I'm not the best person for advice on this part).

Good luck and whatever decision you make, it will be a beautiful day!

Nope, not rude at all! It's become more common to have a closed ceremony and a large reception to celebrate with your friends, even on different days

If you want to do the hiking thing I would definitely have the ceremony private so that all your guests aren't expected to do the hike.

Thanks for all the responses ! I feel much better about it now I think we can do it!

I would just plan on guests not attending both days if you split ceremony/reception into two days and invite guests to both. There is nothing wrong with eloping and having a reception later.

Hey Megan! Is this what you have decided to do for your wedding?

I love the idea!!
